检查dataframe列是否具有unicode

在python3中, str

你的密码, df['fieldname'].str.isascii ,返回一个序列,该序列包含正确或错误的行。因为您想检查该列是否至少有一个 str 值,您可以进行如下检查:

import pandas as pd

df = pd.DataFrame(
    {
        'text': [1, 2, '3'], # '3' is str here.
    }
)

if True in df['text'].apply(lambda x: x.isascii() if isinstance(x, str) else False).to_list():
    print('at least one ascii')
else:
    print('no ascii')
# at least one str -> this will be printed because '3' is ascii.
